Hi,
The most time consuming and annoying part of Revit UI is "Project Browser". I am sure revit users spend large portion of their working time to scroll in Project Browser.
It is very common, a Revit project file has more than hundreds of sheets and views. In that case, if a Revit user wants to add a view into new sheet. He or she has to scroll long list with views, sheets and families etc to find the view what the user wants to drag into the new sheet.
Please imagine, if there are 100 sheets and each sheet has 5 views, how much time does the user need to scroll? It is absolutely a waste of time to go through all unnecessary items in the list of Project Browser. Unfortunately, this situation happens always whenever a Revit user wants to find something in Project Browser.
If Revit allows a user to split Project Browser into each individual floating panels such as Photoshop panels, it can save a lot of users' time to scroll in Project Browser.
Please check Photoshop UI as reference for this idea.
Thank you.
